Series Description: This report summarizes the history of contaminant releases, primarily cesium-137 and mercury, from the 1950s to the 1980s and previous studies that identified the transport, accumulation, and fate of contaminants released to offsite areas from ORNL. It indicates that Poplar Creek and the Clinch River served as pipelines for contaminants released from ORR and that the Watts Bar Reservoir was the major zone of contaminant accumulation. The report also documents the results of the first phase of the Clinch River Resource Conservation and Recovery Act (RCRA) Facility Investigation, which records the "nature and extent" of the Oak Ridge Reservation-derived contamination at offsite locations in the area using radiocesium to identify accumulation patterns and areas of potential hazard to human health. Measurements for cesium are usually given in picocuries per gram (pCi/g), and mercury measurements are given in micrograms per gram.
